DV-33512 with Dual Sync References and Redundant NR Operation

Figure 54.

In this application, two sync references are looped through the SR-

33500, the Primary NR board, and the Secondary NR board. The NRs

are operated in redundant mode. If the Primary board fails the system

will switch automatically to the Secondary board. If both NRs are

removed, Sync Lines 1 and 2 will automatically switch to the SR board.

Note that Sync Line 1 is always combined with Sync Line 3 and Line 2

combined with Line 4. When configuring the output boards, only “Bus

1” and “Bus 2” are valid selections.

Broadlinx operation is also redundant.

For a discussion concerning which of the two sync references should be

connected to the control system, see
